General and Desktop

The URLs passed to QTextEdit::loadResource() in my project are qthelp://<namespace>/<virtualFolder>/<relative path...>. Based on this, I presume that sharing between namespaces can be accomplished referencing an absolute path including the namespace and virtual folder, or a relative path that ascends the parent hierarchy as appropriate. An alternative is to check for script.js in every request. Edit: QUrl::host() reports the namespace. A relative path using ../ doesn't appear to be an option.

@John-Van You are only setting the style sheet set on btn_min but complaining about the changed style of other icons. Perhaps you could post a self-contained, complete example that reproduces the failure. BTW, I'd try removing the half-reference to #btn_max from the style you attached to btn_min.

@Rockerz As Christian said, it's always a good idea to do basic debugging before you ask other people to take a look. You'll generally get much more useful feedback when you say things like where it's crashing and what sort of crash it is. That said, the QPixmap constructor that takes a const char* doesn't take a filename: https://doc.qt.io/qt-6/qpixmap.html#QPixmap-4 I dunno if that's your issue. But it certainly is one of your issues.

@8Observer8 Hi, The module has been deprecated and is not supported anymore. You can check this fork of the original reboot project. Its author might be more able to help you.

@Nirbhik I don't think there are any QML example apps for serial port communication. There is anyway nothing for serial port in QML. You will have to use the C++ classes (https://doc.qt.io/qt-6/qtserialport-index.html) and use usual communication between C++ ans QML.

@Redman said in RemoteObject stops working after wrapping the replicanode: ROReceiver::ROReceiver(QUrl registryUrl) { m_repNode.setRegistryUrl(registryUrl); QSharedPointer<SimpleSwitchReplica> ptr; ptr.reset( m_repNode.acquire<SimpleSwitchReplica>()); // acquire replica of // source from host node R_SimpleSwitch rSwitch(ptr); } C++ basics - how long does R_SimpleSwitch rSwitch(ptr); live?

@SimonSchroeder Although possible, I doubt that rsync sends the password prompt to standard output. More likely standard error or directly to controlling terminal. And if you read my post you will see that it is possible/likely that it only prompts if stdin is a terminal. I think you are incorrect about the event loop and the signals when QProcess::waitForFinished() is called. Although I said it might be best not to use this if attaching signals, if you test it I think you will nonetheless find that all the signals work. OP's output already shows all the other signals are being delivered, I think there is nothing to read from rsync. waitForFinished() does not block the event queue, it runs its own loop.

@Markeggi said in add C++ objects in Qt gui: how can I create a new Widget in the mainwindow.cpp Widgets should have a parent set upon creation (which would most likely be your main window in this case). Adding widgets to layouts also reparents them to the layout's widget. You should be using layouts for everything. One way is to call setCentralWidget() on the main windows to set the widget which is the main part of the main windows. Otherwise set a plain QWidget as the central widget, add a layout to it and then add your widget from the Qt Designer and your own widget to the layout.

I'm a little late to the party 😉. I have a comment about the original problem that there are some libraries which are dynamically linked. This could be solved for the Qt libs through recompilation (like you are trying), but it doesn't solve it for the other libraries. In any case it is a good idea to create an AppImage that has all the libraries included. In this case you can even include the Qt dynamic libraries into the AppImage. We are using a combination of linuxdeploy and linuxdeployqt to create the AppImage. In the end you have a single file that just looks like an executable to the end user (it is actually an executable which will mount the AppImage and run a specific command after that).

@JohnLocke A hint about how you have installed these in the first place might be useful.

@mipr did you find solution? Release build does not work, development is OK.

@vibelin hi, Either: Use a MinGW build of OpenCV Use Visual Studio (and a VS Qt build)

Hi, Yes Yes That noted, there might be several ways to do that depending on the model you use. However, the classic way to do that is to use the serial port to exchange data as well as control the device.

@human99 Ok, thx for the investigation. I'll take a look on it - it should default to debug-and-release to avoid the problems you've encountered.

I really wonder why there is a documentation when noone is reading it. Static pluigins Q_IMPORT_PLUGINS

@NightShadeI This is the workaround I was able to end up doing class ZeroSpaceGrid : public QGridLayout { public: explicit ZeroSpaceGrid(QWidget* aParent) : QGridLayout{aParent} {} QSize minimumSize() const final { return QSize{0, 0}; } }; I don't like it though. Surely there must be a nicer way to have 2 rows of items, and not have the one with content margins stick around constantly given its min size is non-zero? This feels a hit hacky.
